Electromagnetic frequencies are emitted by every electrical device and interfere with the bioelectric signals that our cells use to communicate and complete their biological processes. This leads to a wide variety of health problems and can greatly impede the detoxification process. The VIVOBASE family of EMF protection devices create a natural sferic field that rejuevenates the water in your skin to prevent harmful frequencies from entering your body and interfering with your health. To measure the effectiveness we use an Espion skin antenna test. Sources of EMF include: WiFi, cell phones, computers/ laptops, cell towers, tablets, Smart TVs, Bluetooth, smart meters, baby monitors, security systems, electric cars, smart watches, clock radios, solar panels, dirty electricity, and more. Again, every electrical device emits them. That's just the nature of technology! Symptoms of EMF exposure include: Fatigue, digestive disturbances, a weak immune system, lack of concentration, metabolic disorders, stress, sleep problems (i.e., waking up groggy, troubling falling/ staying asleep), skin problems, headaches, tinnitus, tumors, arrhythmia, and anxiety. Everyone is affected by EMF, and often we do not notice that we have been experiencing symptoms until after we have been protected for several weeks. The VIVOBASE Mobile provides a 1.5-meter radius of protection so that you can be protected on the go. It's a rechargeable device with a lithium-ion battery, and it comes complete with a charging cord and plug. The Mobile device will hold a charge for up to two days. Stay protected when you are on the go.Effectiveness can not be measured using EMF meter because the unit does not block, hormonize, or absorb EMFs. Creates a natural sferic field, does NOT emit a frequency. Rechargeable, portable size, protects you while you're away from home. 1.5-meter radius of protection. Certified by the Bion Institute for its Protective Influence on the Human Organism.
